Jelmer Tiete has designed a development board for the TI CC2538, that is available at GitHub: It’s a nice little system-on-chip with an ARM Cortex M3, 2.4 GHz 802.15.4 radio and it runs at 32 MHz. Perfect for all your favorite Internet Of Things (IOT) shenanigans. Contiki supports...

Linear Technology Corporation announces the LTC3815, a high efficiency 6A monolithic synchronous step-down DC/DC converter with an I2C-based PMBus interface for digital power system management (PSM). The LTC3815’s simplified and intuitive PMBus “Lite” command set makes it simple...

TheTwim @ instructables.com show us how to make a cheap ESP8266 Arduino Shield This is just the first step to make a cheap Arduino WiFi shield using the ESP8266 module. With few more electronic components and the WiFiEsp library you can build it for less that 10 USD. Cheap Arduino...

theorycircuit @ instructables.com shows us how to use TSOP 1738 IR receiver with your Arduino Board. By using arduino and IR Receiver TSOP 1738 (in our project, you can use any ir receiver available) we can decode any infrared remote code into hex or some other format. Before...

MTaylor @ sparkfun.com takes a look inside different power supplies he has on his box. Power supplies are everywhere these days. With the advent of switching power supplies, the cost of high-current supplies has radically dropped. Maybe you’ve noticed how the large, heavy,...

Jaanus Kalde wanted to know why his SRF01 sensor fails after dropping from the air so he did a reverse engineering on it. I needed small ultrasonic sensors for a flying sensor. So I got the smallest one - SRF01. Quite nice unit, works down to 0 cm. There were some problems with it -...

Phillip Schuster has build a portable device featuring some ports to connect stuff like sensors and other circuits and some menu driven user interface to trigger various modules doing tests, reading data etc. Working in my lab with electronics I came across different little...
